Received end of stream when playing a continuous playlist #78

Open floppy-disk opened 4 years ago

floppy-disk commented 4 years ago

Hey all, I upgraded to the latest dev release, and ever since, I intermittently get this issue on all of my channels. I’ve tried to adjust various settings to no avail. I was using a custom ffmpeg that allowed Intel QuickSync transcoding on the master branch, and I’ve tried using the same in dev. I get the same error as below. While the stream cuts out, it recovers after about 10-15 seconds.

Any thoughts?

Jul 15 15:08:03 pseudo1 pseudotv-linux-x64[202]: This either means ffmpeg could not open any valid streams, or you've watched countless hours of television without changing channels. If it is the latter I salute you.

In order to make all videos part of the same stream, pseudoTV uses ffmpeg to concatenate the files. But ffmpeg concat has a limitation that it's apparently impossible (or really difficult) to make it infinite, so instead pseudo provides the same address 100 times. This means that it's normal behavior for pseudotv to end after playing 100 videos in a sequence.

Now, if there are ffmpeg errors or problems with the videos that cause the ffmpeg playback to end too quickly, it may be exiting videos too early and playing again to replay them, which makes it run out of the 100 video attempts.

Normally when this happens, there's another ffmpeg error way above this one that's more specific to the problem.
